Only enable it for CPUs that support it.
This restores the behavior prior to 7a650caf.

The specification uses lower case most of the time.

Print the UL in code format and in the short format used by the
specification.

Some files set the PreviousPartition field to point to its own offset.

If we are parsing forward the Previous partition is immediately known
and its value could be used, otherwise we can safely point to the
header.
